Abstract
Abstract A building block LSI includes a plurality of circuit blocks and an L-shaped channel formed between adjacent circuit blocks. The L-shaped channel extends in two directions at a first angle. A first set of wires is disposed in the L-shaped channel, extending in a direction parallel to the L-shaped channel. A second set of wires extends at a second angle from the circuit blocks into the L-shaped channel. The second angle is half that of the first angle. The two sets of wires are connected by through-holes such that the circuit blocks are interconnected electrically.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
112 words
A building block LSI comprising: a plurality of circuit blocks; an L-shaped channel formed between adjacent said circuit blocks, said L-shaped channel extending in two different directions from a corner portion of said L-shaped channel, and said two different directions defining a first angle therebetween; a first set of wires disposed in said L-shaped channel and extending in said different directions; a second set of wires extending at a second angle from said circuit blocks into said L-shaped channel, said second angle being half that of said first angle; wherein said first set of wires and said second set of wires are connected such that said adjacent circuit blocks are interconnected electrically.
Claim 2
Dependent Claim
112 words
A building block LSI comprising: a plurality of circuit blocks; an L-shaped channel formed between adjacent said circuit blocks, said L-shaped channel extending in two different directions from a corner portion of said L-shaped channel, and said two different directions defining a first angle therebetween; a first set of wires disposed in said L-shaped channel and extending in said different directions; a second set of wires extending at a second angle from said circuit blocks into said L-shaped channel, said second angle being half that of said first angle; wherein said first set of wires and said second set of wires are connected such that said adjacent circuit blocks are interconnected electrically.
